Abstract
An alignment system for use with a keratoscope to form an eye measurement system uses a source of a light beam which is directed towards a cornea. A reflection from that beam is supplied to first and second quadrant detectors which are connected to circuits to generate an output when the cornea is properly aligned. Upon proper alignment, the system triggers the calculation of the cornea shape by the keratoscope.
